In two months, Petra caught 10 account compromises with zero false positives. I don't need any whitelists, even with tenants who regularly use VPNs. If your tenants use Microsoft, you should be using Petra.

What sets Petra apart?

Microsoft specialists.

Our narrow focus lets us achieve best-in-class detection of Microsoft attacks. P1/P2 not required. Petra catches what P2 and others miss.

Correlated across everything.

Petra tracks attacks across Active Directory, Exchange, Sharepoint, Teams, and more--over a full year of activity. Wherever attackers try to hide, Petra is built to catch them.

Effortless security.

No Business Disruption

With industry-leading accuracy, Petra is able to lock out attackers while keeping employees safely logged in. But don't take our word for it, let us show you.

No Business Disruption

Math that feels like magic.

Learn about the high-powered data science that powers our industry-leading accuracy and speed.

Adaptive fingerprinting

We turn low-information logs (7-9 data points) into high-information adaptive fingerprints (~600 data points). Each fingerprint incorporates a full year of activity.

Columnar data store

We use a columnar data store. We trade-off being able to edit logs after they're written, and instead get a massive efficiency gain for large-scale machine learning. Last year's "too expensive" is now affordable.

Advanced machine learning models

We train specialized detection and critic models to sift through tricky benign patterns, filter out the noise, and find emerging threats like token theft.

Our grind, your glory.

Customizable reports that win you new deals and dazzle existing customers.

Security assessments that show real value

Get a security assessment included in your pilot, branded to show your customers that you’re a cyber expert.

Threat hunting that gets results

In 92% of assessments, we identify the specific threat actors knocking at the door.

Petra has a history of finding stealthy attackers, even if they’ve been lurking for 50+ days.

Suspicious activities and trends

For your QBRs, we compile suspicious activity and active threats, so you always have something to impress your clients.
